My invention relates to con'densers and my i furnaces, and for'condensingand collecting volatilized ores which escape with the gases-V from ore roasting furnaces.

A further object is to provide an apparatus Which Will create a draft through the furnace and dispose of the gases and other products of combustion, Without employing i a smolre stack for Vthat purpose.

Other objects Will hereinafter appear, and in order that the invention may be fully understood reference Will new 'be had to the Vaccompanying drawing, in Which:

Fig. 1 is a vertical longitudinal section of the apparatus on line- I-I of Fig. 2.

Fig. 2 is a horizontal longitudinal section on line Ill-II of Fig. 1.

Fig. 3 is an end View of the apparatus.

Referring now in detail to the various parts7 2 designates a chamber which may be constructed of any suitable material such as sheet metal,'1nasonry, etc., and embodies top and bottom Walls l and 6, front and rear walls 8 and 10,y respectively, and side Walls 12. A door 14 slidably mounted in guides 16y is provided at the front of the chamber 2, so that access maybe readily had to the interior thereof.

The upper front portion of the chamber 2, has an inlet pipe 18 and its rear lower portion an outlet pipe 20. The inlet pipe 18 is adapted to be connected to the flue A of a furnace B. Said furnace B may be of any Well-known type such, for instance, as a heating furnace, an ore roaster, etc. The outlet pipe 20 is connected to suitable suction means such as a fan 22 having an out-' let 24 and driven by an electric or other suitable motor 26.`

28 designates a plurality of superimposed. trays removably arranged in the chamber 2 on slides 30. The trays 28 have open mesh bottoms 32 for vthe passage of Water discharged from spray nozzles 34 arranged 1n the upper portion of the chamber 2 and connected to a manifold 36, Which in turn is connected to .a valve-controlle supply pipe 38.

i() designates a tray removably arranged and provided Withay closed bottom -portion 12. v f

Z111 designates a drainage trap leading from the bottom of the chamber 2 to carryfoifthe overflow from the tray 40 `Without admitting air to said chamber. A y

Wheny theY chamber 2 is connectedjoQa furnace used for domestic or industrial heating purposes the` suction Vfan 22 is started up to create a draft in said furnace and ythrough the chamber 2. As the products of combustion from the furnace enter the* chamber 2 they are subjected to the spray from the nozzles 34, the spray condensing the-volatilized solids in the products of combustion and` precipitating them upon the trays 28 and 32. The spray also cleanses the gases of smoke and obnoxious odors so that that portion of the products of combustion which escapes through the outlet pipe 20 is both colorless and odorless. Ifvdesirable the spray may be chemically treated'to render it more effective in dissipating the odors and rendering the gases harmless to animal and plant life. At intervals when the furnace is not in operation the door 14 may be opened and the trays 28 and 32 removed With their contents which may then be dried and reused for fuel.

When the chamber' 2 is vconnected to an ore roasting furnace the trays 28 'are preferably supplied with coke or V'some other agenthaving an affinity for the volatili'zed metals which enter the chamber 2 with the products of combustion. As the volatilized -ores are precipitated by the spray theyare caught by the coke 'to which they adhere,V While the carbon forming part of theproducts of combustion, having little or no affinity for the coke, is carried by the spray to the bottom tray 40, so that after being dried it may be used with other fuel in the furnace. On completion'of the roasting operation the trays 28 may be removed from the chamber 2 and their-.contents placed in arcrucible in which the coke may be consumed to free the metal. p

From the foregoing description itis apparent that I have provided an apparatus which will not onlyV eliminate the smoke nuisance but Will also collect for reuse carbon yand other combustible solids precipitated from the products of combustion drawnv from the furnace. It is also apparent that upon the bottom Wall 6 of the chamber 2 I have provided a compact and economical appliance for recovering volatilized ores which is more eiiicient and occupies considerable less space than the apparatus usually employed for that purpose.

lVhile I have. shown and described the preferred construction, combination and arrangement of parts7 i reserve the right to make such changes as properly fall Within the spirit and scope of the invention as claimed.

Having thus described my invention, What I claim and desire to secure by Letters Patent, is:

In an apparatus of the character described a chamber having an inlet at its upper portion for connection with the flue of a furnace, an outlet to said chamber near the lower portion thereof, means adjacent to the outlet for creat-ing a draft through said chamber to draw the products of combustion from said furnace, a plurality of spray means extending across the upper portion of the chamber for precipitating therein the volatilized solids in the products of combustion7 superimposed trays mounted in said chamber having openings in their bottom portions and provided With an agent having an aiiinity for certain of said solids, an imperforate removable tray resting upon the bottom of the chamber, and drainage means leading from said chamber.

In testimony whereof l affix my signature.
